"A lot of people don't realize that the industry that gave the most money to Washington over the past few years is not the oil industry, it was not pharmaceuticals, it was consumer credit products, those are the people, the credit card companies have been giving money and they have influence... The credit industry has spent tens of millions of dollars lobbying and as their profits grow they just throw more into lobbying for how they can get laws that will make it easier and easier and easier to drain money out of the pockets of middle class families." - Senator Elizabeth Warren

It's no surprise that Washington is corrupt. There is a revolving door for powerful individuals between Wall Street and the White House. It's also no surprise that Hillary Clinton's top supporters are multinational banking firms.

Here are Hillary Clinton's top campaign contributors according to opensecrets.org.

1. Citigroup Inc - an American multinational investment banking and financial services corporation. By November 2008, Citigroup was insolvent, despite its receipt of $25 billion in tax-payer funded federal Troubled Asset Relief Program funds. On November 24, 2008, the US government announced a massive stimulus package for Citigroup designed to rescue the company from bankruptcy while giving the government a major say in its operations.

2. Goldman Sachs - an American multinational investment banking firm that engages in global investment banking, securities, investment management, and other financial services. "At best, it's considered a revolving door for powerful individuals between Wall Street and the White House. At worst, it's an economic coup that has been successful in infiltrating and subverting the United States federal government. And more and more, its employees and the federal government’s employees are becoming one and the same." whiteoutpress.com

6. EMILY's List is an American political action committee (PAC) that aims to help elect pro-choice Democratic female candidates to office. It was founded by Ellen Malcolm in 1985.

7. Time Warner - The world's third largest television networks and filmed TV & entertainment company in terms of revenue (after Comcast and The Walt Disney Company), and at one time was the world's largest media conglomerate.
